.SPECIFICATION forming part of Letters Patent No. 442,831, dated Becember 16, 1890.

Application tiled May 6, 1890. Serial No. 350,776. (No model.)

To aZZ whom z'ft may concern:

Be it known that I, WILLIAM S. SHARP- NECK, aeitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented .certain new and useful Improvements in Journal- Boxes, ot' which the following` is a specification, reference being had therein to the accompanying drawings.

This improvement is designed more particularly for journal-boxes such as are shown in my patent, No. 392,465, dated November 6, 1888; and the invention consists in the peculiar construction, arrangement, and combination of parts hereinafter more particularly described and 'then definitely claimed.

In the accompanying drawings, Figure 1 represents a vertical central section of myimprovement; Fig. 2, an elevation of a nut used 2o therein. Fig. 3 is a face view of the same nut.

Referring now to the details of the drawings by letter, 1 represents the end of a caraXle, preferably provided with a removable wearing-plug 2. Opposite this plugis a ball 3,

which runs in a recessin a plug 4,which sets in an aperture in the front of the casing ,which casing'is intended to be secured in position in any suitable manner. This plug Li has a threaded shank 6, on which is screwed a nut 3o 7, having grooves 8 cut in its face, as shown clearly in Figs. 2 and 3. Through the center of the piug is cut a keyway 9, through which, l the grooves 8, and a corresponding groove 10, l

gin to showr signs of Wear it becomes neces- 4o sary to set the ball 3 closer to the bearingpiece 2. To do this, the plug, key, and nut are removed and a liner (indicated in dotted lines) is set between the head of the plug 1i and the casing 5. The nut is then screwed home and the key inserted in the aperture formed by the grooves 8 and 10 and through the keyway 9 in the shank of the plug. By this means a perfect adjustment of the relative position of the ball and bearing-piece 5o may be readily obtained by a device that is cheaply made, yet strong and not liable to get out of order.

Vhat Iclaim as new is- The combination, with the nut 7 and casing 55 5, grooved as described, of the key 11 and headed and threaded plug 4, having a keyway 9, substantially as described.

In testimony whereof I afiix my signature, in presence of two witnesses, this 5th day of 6o May, 1800.
